Introduction

Preanalytical control and monitoring continue to be an important issue for clinical laboratory professionals. The aim of the study was to evaluate a monitoring system of preanalytical errors regarding not suitable samples for analysis, based on different indicators; to compare such indicators in different phlebotomy centres; and finally to evaluate a single synthetic preanalytical indicator that may be included in the balanced scorecard management system (BSC).

Materials and methods

We collected individual and global preanalytical errors in haematology, coagulation, chemistry, and urine samples analysis. We also analyzed a synthetic indicator that represents the sum of all types of preanalytical errors, expressed in a sigma level. We studied the evolution of those indicators over time and compared indicator results by way of the comparison of proportions and Chi-square.

Results

There was a decrease in the number of errors along the years (P < 0.001). This pattern was confirmed in primary care patients, inpatients and outpatients. In blood samples, fewer errors occurred in outpatients, followed by inpatients.

Conclusion

We present a practical and effective methodology to monitor unsuitable sample preanalytical errors. The synthetic indicator results summarize overall preanalytical sample errors, and can be used as part of BSC management system.Key words: Preanalytical phase, errors in laboratory medicine, balanced scorecard, patient safety  相似文献   

The use of intellectual capital to obtain competitive advantages in regional small and medium enterprises     

Carlos M?JardonEmail author 《知识管理研究与实践》2015,13(4):486-496

Entrepreneurs use resources and capacities to form core competencies. These are competitive advantages if they produce better company performance. Intellectual capital (IC) is a key resource for competitive advantage. This paper analyses the process through which entrepreneurs use this resource to obtain competitive advantages in regional SMEs. We show how entrepreneurs constitute three core competencies with IC and territory: internal knowledge management, relationship management and innovativeness. By partial least squares techniques we demonstrate that: (i) the two first factors influence innovativeness; (ii) this dynamic affects company performance. The study contributes to the analysis of the process of building core competencies by the entrepreneur from IC, in order to get better company performance.  相似文献   

Teachers' Prestige in Spain: probing the public's and the teachers' contrary views     

Víctor Pérez-Díaz  Juan Carlos Rodríguez 《European Journal of Education》2014,49(3):365-377

We use the results of a public opinion survey we carried out in 2012 on a sample of the Spanish adult population to offer a plausible explanation of one of the main conundrums of primary and secondary school teachers' prestige, not only in Spain, i.e. that, contrary to public discourse and to teachers' perceptions, this prestige has not fallen in the last decades, but has remained middle to high. The estimates of teachers' prestige made by the public are the same (roughly, around 70 in a 0 to 100 scale) as those that were measured in the early 1990s. However, a clear majority of the public believes that teachers' prestige has fallen in the last decades, reiterating a cliché that is widespread in the Spanish public sphere, especially among teachers. We hypothesise that the perception of the falling prestige is much more a matter of a public space dominated by the media than of a public space that is more confined to everyday experiences and to the citizens' basic values. We support our hypothesis with pieces of empirical evidence related, on the one hand, to the association of that perception with media consumption variables in our survey, and, on the other, to media (negative) treatment of teachers' prestige. In our argument, we are also helped by a literature that is not usually dealt with in studies of teachers' prestige: that of media influence in the formation of public opinions regarding other people's opinions.  相似文献

Accuracy,intra- and inter-unit reliability,and comparison between GPS and UWB-based position-tracking systems used for time–motion analyses in soccer

There is interest in the accuracy and inter-unit reliability of position-tracking systems to monitor players. Research into this technology, although relatively recent, has grown exponentially in the last years, and it is difficult to find professional team sport that does not use Global Positioning System (GPS) technology at least. The aim of this study is to know the accuracy of both GPS-based and Ultra Wide Band (UWB)-based systems on a soccer field and their inter- and intra-unit reliability. A secondary aim is to compare them for practical applications in sport science. Following institutional ethical approval and familiarization, 10 healthy and well-trained former soccer players (20?±?1.6 years, 1.76?±?0.08?cm, and 69.5?±?9.8?kg) performed three course tests: (i) linear course, (ii) circular course, and (iii) a zig–zag course, all using UWB and GPS technologies. The average speed and distance covered were compared with timing gates and the real distance as references. The UWB technology showed better accuracy (bias: 0.57–5.85%), test–retest reliability (%TEM: 1.19), and inter-unit reliability (bias: 0.18) in determining distance covered than the GPS technology (bias: 0.69–6.05%; %TEM: 1.47; bias: 0.25) overall. Also, UWB showed better results (bias: 0.09; ICC: 0.979; bias: 0.01) for mean velocity measurement than GPS (bias: 0.18; ICC: 0.951; bias: 0.03).  相似文献
